Definitions

  • the present disclosure relates to a device and method for facilitating secure fuel delivery to a vehicle and, more specifically, to such a device and method that optimizes wireless communication between a vehicle and a fuel authorization system to reduce communication failures between a reader/interrogator associated with the fuel authorization system and a wireless communication tag associated with each vehicle, while ensuring the integrity of the fuel delivery process, simultaneously reducing instances of fuel theft and accommodating vehicles of varying physical geometries.
  • the authorization server may authorize fuel delivery with the pump nozzle removed from the vehicle fuel tank delivery neck.
  • a read range that is too large permits theft by allowing separate and discrete fuel containers, and even other vehicles located nearby, to receive fuel.
  • the read range between the reader and the tag should be small enough to require the fuel delivery nozzle to be inserted in the vehicle fuel tank delivery neck before the reader can recognize and identify the vehicle tag.
  • communication should end and fuel delivery should terminate.
  • a read range that is too small can give rise to other wireless communication problems between the reader and tag. For example, physical orientation of the reader antenna relative to the tag antenna influences communication, as does the physical configuration of the vehicle proximate the fuel tank delivery neck and the large amount of metal comprising the vehicle itself.
  • WO 2008/090539 A2 describes devices and methods for authorizing purchases associated with a vehicle.
  • US 2016/012261 A1 describes an RFID reader and a method for securing fuel delivery with a fuel dispensing nozzle.
  • GB 2 400 364 A describes means for preventing a motorist filling a vehicle with the wrong type of fuel.
  • a connector for attaching a radio frequency identification (RFID) reader to a fuel dispensing nozzle.
  • the connector comprises a bracket affixed to and surrounding a fuel dispensing nozzle, at least a portion of the bracket is configured to rotate relative to the nozzle while another portion of the bracket remains fixed relative to the nozzle; and a housing is affixed to the bracket and configured to receive an RFID reader.
  • the housing is repositionable by rotating the bracket and housing relative to the fuel dispensing nozzle. The repositioning of the housing can be done with the fuel delivery nozzle positioned in the fuel inlet of the vehicle or outside of the fuel inlet of the vehicle.
  • a connector for attaching a radio frequency identification (RFID) reader to a fuel dispensing nozzle.
  • the connector comprises a collar assembly configured to surround and engage a fuel dispensing nozzle; a rotating bracket assembly engaged with the collar assembly and configured to rotate relative to the collar assembly; and a housing affixed to the rotatable bracket and configured to receive an RFID reader.
  • the housing is repositionable by rotating the rotating bracket assembly and housing relative to the collar assembly and fuel dispensing nozzle. The repositioning of the housing and the rotating bracket assembly can be done with the fuel delivery nozzle positioned in the fuel inlet of the vehicle or outside of the fuel inlet of the vehicle.
  • an embodiment of a connector where a fixed collar assembly is mounted to a fuel dispensing nozzle, a rotating bracket assembly interfaces with and rotates relative to the fixed collar assembly and an RFID housing is connected to the rotating bracket such that the RFID housing and rotating bracket rotate relative to the fixed collar assembly to reposition the RFID bracket and the housing relative to the vehicle in which the fuel dispensing nozzle is positioned.
  • One or more stabilizing members are provided to stabilize or hold the position of the rotating bracket assembly at discrete orientations or positions relative to the collar assembly, but also allow the rotating bracket assembly to move between the discrete positions.
  • a radio frequency reader or reader module is contained within the housing and designed to communicate wirelessly with a radio frequency tag associated with a vehicle.
  • the tag is positioned proximate the fuel receiving inlet, but may not be positioned consistently among different vehicles. Improved communication between the reader and the tag may be available if the reader is repositionable relative to the tag. For this reason, the reader housing, containing the reader or reader module, is repositionable relative to the fuel dispensing nozzle and the vehicle.
  • a stabilizer or stabilizing member comprises a biased ball bearing and detent system.
  • a fixed collar assembly is secured to a fuel dispensing nozzle.
  • the collar assembly comprises one or more collar members affixed to the nozzle and one or more bushings affixed radially outward of the collar members.

  • a rotating bracket assembly surrounds the collar assembly.
  • One or more bearings are positioned in the rotating bracket assembly and the one or more bearings are biased inwardly toward the collar assembly to interface with the detents.
  • the rotating bracket assembly When one or more bearings are positioned in a detent, the rotating bracket assembly is stabilized and the RFID housing stays in a set position.
  • the strength of the bias is adequate to hold the housing in position, but not so strong as to inhibit movement or repositioning of the RFID housing from one position to another position.
  • the bias may be provided by a coiled spring or other structures known to those of skill in the art to bias the bearing inwardly toward the detents.
  • the biasing member and one or more bearings may alternatively be disposed in the collar assembly and the detents positioned along a surface of the rotating bracket assembly that is proximate the collar assembly.
  • the stabilizing members can be arranged such that the housing can move between fixed angular positions, for example every 15 or 30 degrees, and can move in either direction, clockwise or counterclockwise. The number of biased bearings and detents and their position can vary.
  • the stabilizers or stabilizing members comprise first and second sets of attracting magnets.
  • the magnets stabilize the position of the rotating bracket assembly and RFID housing relative to the fixed collar assembly at discrete locations while also permitting movement of the rotating bracket assembly between the discrete locations.
  • a first set of magnets are positioned in the collar assembly with each individual magnet spaced from adjacent magnets.
  • the second set of magnets is positioned in the rotatable bracket assembly and magnets are spaced apart.
  • the rotatable bracket is stabilized in a fixed position when at least some of the first and second magnets are radially aligned.
  • one of the first and second set of magnets may be a single magnet.
  • the attractive force between the magnets is sufficiently strong to hold or stabilize the position of the rotatable bracket assembly.
  • the attractive strength between the magnets is not too strong that it cannot be overcome by manually moving the rotatable housing to the next position.
  • the magnets can be arranged such that the housing can move between fixed angular positions, such as every 15 or 30 degrees, and can move in either direction, clockwise or counterclockwise. The number of magnets and the position where the magnets are aligned can vary.
  • the stabilizers or stabilizing members may act axially relative to the fuel nozzle rather than radially.
  • detents could be formed in the side walls of the collar assembly and the one or more biased bearings are positioned in the rotatable bracket assembly to engage the detents.
  • the one or more bearings would be biased axially to move in and out of the detents.
  • the one or more biased bearings could be positioned in the collar assembly and the detents located in the rotatable bracket assembly, but the movement of the one or more bearings remains in the axial direction.
  • the stabilizing members being magnets
  • the magnets may be disposed within the collar assembly and the rotatable bracket assembly to align axially rather than radially relative to the fuel nozzle.
  • the RFID housing may also be configured to move linearly, along the fuel dispensing nozzle. Repositioning of the RFID housing thus may be rotational, linear or both.
  • the collar assembly may comprise a releasable clamping mechanism allowing the connection between the collar assembly and the fuel dispensing nozzle to be loosened, repositioned axially along the nozzle, and reengaged.
  • a guide may be positioned along a length of the nozzle and the collar assembly configured to move linearly along the guide.
  • a method for enhancing the wireless communication between a radio frequency identification (RFID) tag associated with a vehicle and an RFID reader associated with a fuel delivery system comprises providing a bracket configured to attach to a nozzle of a fuel delivery system; attaching the bracket to the nozzle of a fuel delivery system; attaching to the bracket a housing configured to hold an RFID reader; and repositioning the housing and at least a portion of the bracket relative to the nozzle.
  • the method also includes repositioning of the housing with the nozzle positioned in the fuel inlet of a vehicle.
  • embodiments permit changing the frequency of the RFID reader antenna to match the frequency of the RFID tag associated with the vehicle.
  • the resonant frequency of the reader antenna and tag antenna can vary with changes in temperature. Because the RFID reader and tag are located outside each is subject to a wide variety of changes in environment. However, the reader resonant frequency does not change nearly as much as the resonant frequency of the tag. Therefore, being able to vary the frequency of the reader antenna to match that of the tag antenna improves communication.
  • the reader antenna can be altered by a microcontroller sensing the temperature via on-board temperature sensors and then adjusting the operational frequency of the reader via firmware configuration of the microcontroller which controls the RFID reader to correspond to the assumed frequency of operation of the tag.
  • a plurality of temperature zones will be defined. In one embodiment there may be three temperature zones. In the middle temperature zone (which may extend for example from -10°C to +40°C, the reader will operate at a predetermined frequency (e.g., 125kHz). Above +40°C the system will change the operational frequency to a second predetermined frequency (e.g., 121kHz), and below -10°C the system will change the operational frequency to a third predetermined frequency (e.g., 129kHz). It should be appreciated that the number of zones and the predetermined frequencies may vary.
  • the system microprocessor may be configured to permit the microprocessor to optimize communication with the tag by scanning through a plurality of RFID frequencies and identifying the frequency which best suites communication with a specific vehicle tag.
  • communication performance may also be improved by adding shielding to the RFID housing to address potential sources of interference with communication between the RFID reader and tag.
  • This may be accomplished in a number of ways as would be known by a person of ordinary skill in the art.
  • biaxially-oriented polyethylene terephthalate (BoPET or Mylar) may form an effective shield.
